Abstract
The process for removal of arsenic from waste waters is characterised by
(A1) precipitation of the arsenic in the form of sparingly soluble calcium magnesium arsenates by addition of calcium compounds and magnesium compounds to the waste water at pH 2 to 12 and
(A2) removal of the calcium magnesium arsenates
and/or
(B1) contacting the waste water with an ion exchanger at pH 2 to 12
and optionally
(B2) regeneration of the ion exchanger after reaching the limit of the capacity
and/or
(C1) adsorptive removal of the aresenic by contacting the waste water with activated carbon at pH 2 to 11
and
(C2) removal of the charged activated carbon alone or together with precipitation products.
<??>The process permits removal of arsenic, in particular even in the case of waste waters that are difficult to treat and contain heavy metals such as lead, and also sulphate, to residual contents < 0.3 mg AS/l.
